DensGlass® Sheathing disrupted the way commercial buildings are designed over 30 years ago, and now DensElement® Barrier System continues that legacy of innovation by integrating 3 products in one: gypsum sheathing, water-resistive barrier and air barrier. AquaKor™ Technology creates the WRB-AB within by integrating the fiberglass mat and gypsum core to form a monolithic, hydrophobic surface that blocks bulk water but allows vapor to pass through, eliminating the need for a separate WRB-AB.
